(01. err-50y
This invention relates to improvements in
windows and more particularly windows of the
double-hung sash type.
‘Such windows are universally popular despite
the fact that they have a number of inherent
disadvantages. When the sashes are m‘ovedinto
positions with one directly behind the other, the
relation which opens the window‘ as wide ‘as pos
sible, one half of the open area of the window
10 frame is blocked by the sashes.
This seriously
affects the ventilation in warm weather, often
making it difficult to cool 01? bed rooms on Sum
>mer evenings even after the air out of doors has
become comfortably cool.
‘
.
Washing the outside of double-hung sash win.»
dows is di?icult when attempted from inside the
building. First floor windows can sometimes be
reached from the ground, but in the 'absence'of a
porch roof, balcony, or other standing room, win
20 dows above the ?rst floor can be washed ef?
ciently only by climbing through the: window
frame and sitting or standing‘ on the sill outside
the window. For most housewives this is too
strenuous and dangerous, and the result is that
25 upstairs windows are'either left dirty or the wash
ing done by a workman who must be ‘paid for the
job.
windows, but'casement windows have disadvan
30 tages of their own.
They are much more likely
to leak and areldif?cult to weather strip ‘effec
vtively. If a casement window swings inwardly it
takes up space in the room, and furniture must
be located so as‘ to leave the window an unob
35 structed arc in which to swing. If the window is
hinged so as to open toward ‘the outside it pre
sents a screening problem.‘ Outside screens can
not be used, and‘an inside screen must not block
access to the window. An inside ‘ screen that
.40 ‘swings may be just as ‘objectionable as an inward
ly swinging casement window.
A sliding sash window with the weight of the
sash counterbalanced will remain in any position
to which it is moved, but a casement window must

It has long been recognized that the ideal win
dow would be one having sashes capable of both
sliding and swinging movement. The desidera~
tum has been a windown having all of the advan
tages of both sliding sash and casement windows.
Many attempts have ‘been made in the past to!
construct such a window, but so far as we are
55 aware all of these attempts have been imprac
‘

It is an object of this invention to provide an
improved window construction which obtains
both sliding and swinging movement of the
sashes.
A ‘more speci?c object of the invention.
is to provide such a construction which can be _
conveniently and economically applied to- existing
double-hung sash windows of the type most com
monly used in wooden buildings. The invention 10
can be applied to ‘existing‘win'dows, and its sim
plicity makes new‘ windows. in which it is em
bodied reasonable in cost in comparison with
ordinary sliding sash windows.
Windows made in accordance with this inven 15
tion are ‘easily operated, can be moved up and
down when swung open as well as when con?ned
by the stile runways, and are counter-balanced
effectively in all positions.

Other objects, features, and advantages of the ,
invention-appear or will be pointed out as the

. The window includes a frame Ill of conven
tional design. An upper sash I I, has a joint near
its left edge com-prising hinges [3 connecting
the “main bodyof the sash with an ‘outer shoe
15 which has‘ the same height and thickness as , 50
the main body ofthe. sash so that when the sash
is closed», (i. e. in position toslide up and down
in the frame) the outer shoe is, in effect, a con
.tinuation of the main body of the sash as shown
in Fig. 5. A ‘weather strip ll attached to the L
2
2,137,053
outer shoe insures against any leakage of air
between the shoe l5 and the other part of the
sash, but the window can be made without the
weather strip |'| if absolute tightness against in
?ltration is not essential.
The outer shoe I5 is recessed to ?t over a track
l9 which is fastened to the pulley stile 20 of
the frame by countersunk screws 2| (Fig. 3) . The
track I9 extends for substantially the full height
10 of the pulley stile.
The recess in the outer shoe l5 has a depth
slightly less than the height of the track so that
the shoe bears against the track and there is a
small clearance between the shoe and the pulley
15
stile.
‘
'
An inner shoe 23 ?ts loosely within the track I!)
and has a ridge 24 which extends through a slot
26 in the track and contacts with the outer shoe
| 5. The inner and outer shoes are fastened to
20 gether by screws 25 which connect the hinge Hi
to the outer shoe and thread into the inner shoe.
The width of the ridge 24 is slightly less than the
width of the slot 26. The height of the ridge
24 is a little greater than the height of the side
25 walls of the slot so that there is clearance for
the edge portions of the track below the inner
and outer shoes. The ridge 24 is preferably in
tegral with the inner shoe 23 but this is not
essential and shims can be used in place of an
30
integral ridge.
The outer shoe |5 slides in the channel or stile
runway between the blind stop 29 and parting
strip 30 in the same manner as the upper sash
of any conventional double hung sash window.
35 The sash H is counterbalanced by a weight 32
connected to the sash by a cable 33 which passes
over a pulley 34 and connects with a hook 36
at the top of the inner shoe 23 as shown in Fig. 6.
Spring balances which are used in place of weights
40 in some modern houses, may, of course, be used
in the same way with this invention. The
counter-balancing of this invention is just as
effective when the sashes are swung open as
casements, as when they slide up and down as
45 ordinary sashes.
A second inner shoe 38, shown in Figs. 5 and
7, is connected to the outer shoe l5 at the level
of the lower hinge l3. The construction and
attachment of the inner shoe 38 is the same as
50 that already described for the inner shoe 23,
except that there is no hook 36 because no
counter-weight cord is attached to the lower
inner shoe 38.
The window has a lower sash 4| which includes
55 an outer shoe 42 (Fig. 2) connected to the main
body portion of the sash by hinges 43 near the
right edge of the sash. The lower sash has an
stile through which access may be had to the
weight pocket of the frame. In applying this in
vention to a conventional window, the removable
portion of the pulley stile is taken out and the
opening enlarged to make it somewhat longer than
the height of the sash. While the pieces cut out
of the stile can be connected with the removable
portion to make the larger movable portion for
this invention, it is more economical to save the
labor by substituting a single piece of wood pre 10
viously cut to ?t the enlarged cut-out portion.
Fig. 5 shows a movable portion 5| of the pulley
stile 20. This movable portion has stop plates
52 fastened to the ' upper and lower ends by
screws 53. These stop plates 52 extend behind
the ?xed portions of the pulley stile 20 above
and below the movable portion 5| and prevent
the movable portion from moving out beyond the
position shown in Fig. 5 in which the surfaces of
the movable portion 5| are flush with the sur
20
faces of the ?xed part of the stile.
The track I9 is made in three sections as shown
in Fig. 8, the lengths of the sections being such
that the breaks 55 correspond with the upper
and lower ends of the movable portion 5| of the
pulley stile.
Springs 51 (Fig. 5) fastened to the ?xed part
of the pulley stile 20 by bolts 58 bear against the
top plates 52 and hold the movable portion 5|
of the pulley stile in its normal forward position 30
shown in Fig. 5.
When the outer shoe I5 is on that section of
the track l9 which is fastened to the movable
portion 5| of the pulley stile the sash | I can be
pushed to the left, against the tension of the
springs 51, far enough to make its edge which
is remote from the hinges |3 come out of the
stile runway in which it slides. The sash is
then free to swing on its hinges l3.
It is necessary for the parting strip 30 to move
back with the movable portion of the pulley stile,
otherwise the hinge l3 (see Figure 3) would strike
the parting strip‘ and prevent the sash from mov
ing back far enough to clear the guide channel
on the other side of the window.
The movable '
portion of the pulley stile on the left hand side
of the frame permits the sash II to move far
enough to the left so that its free swinging edge
clears the hinge edge of sash 4|, when that sash
is swung open, as shown in Figure 1.
The strength of the springs 51 is such that the
sash can be easily pushed laterally to clear the
stile runway on the side away from the hinges
when it is to be swung open in casement fashion,
but the springs 51 are strong enough to hold the
movable portion 5| of the pulley stile in the posi
tion shown in Fig. 5 during the ordinary up and
down sliding movement of the sash. Best results

struction similar to the upper sash already de - are obtained by having the lower spring 51 under
60 scribed, but the track for the lower sash is located
somewhat greater tension than the upper spring in the stile runway in front of the parting strip because the sash is counterbalanced on the hinged

sashes of conventional windows slide.

usual way. Weather stripping 41 is used in these
runways in the illustrated embodiment of the
70 invention. The sashes slide up and down in the
frame, the hinges | 3 of the upper sash being short
enough to pass the lower sash. The window can
be locked closed by the usual window lock 49.
The conventional window frame for double
hung sash has a removable portion of the pulley
springs.
The lower sash 4| has a movable portion 60
of the pulley stile behind the track on which' 70
the lower sash slides. This movable portion 60
is‘ similar in construction to the portion 5|
already described but is, of course, a portion of
the forward runway instead of the rearward run
way. It is a feature of the construction that the

It is anothe‘vrlfeaturerof the invention that the
movable, portions 5| of the pulley stiles are longer
than the heights? of the sashes. This makes it
unnecessary to- locate the sash accurately before
15 pushing it laterally preparatory to swinging it
open.
The invention is not limited to wooden frames
or to the embodiment illustrated in the drawings.
Various changes and modi?cations can be made
20 without departing from the invention as de?ned
in the claims.
We claim:
1. A double-hung sash window including a
frame having a pulley stile on each side, a pulley
near the upper end of each pulley stile, a weight
box behind each pulley stile, and channels on
